Infilled Wall Frame Structure Seismic Analysis

Frame with infilled wall structure is a common structure system. The existing norms andpractices of pure frame model are used in the analysis of the seismic design, for which thefilling wall " non-stress " component uses the wall weight in order to load form the input tothe calculation model, then according to the number of filling wall of frame structure stiffnessand the natural vibration period adjustment; the operation is relatively simple, absolutely,without reasonable consideration filled synergies between the wall and the frame. A lot ofdamage shows that ignore the synergy generated by the filling wall and frame damage is veryserious. From a large number of research and the available data can also see, filled wall offrame system of the bearing capacity, stiffness and deformation performance also has the verybig influence. Therefore, in the seismic structural design, considering the influence of fillingwall of frame is very necessary. Although many scholars have done a lot of research onframework of infilled wall, but there are still many problems to be solved. The main work ofthis paper are as follows:(1) on the basis of theoretical analysis, this paper analysis software MIDAS/GEN wasused to establish the frame infilled masonry shear wall model, the filling wall as shear wallsto resist the horizontal earthquake force calculation and the frame, and parallel, considerfilling different distributions, the number of the wall, the establishment of the correspondingmodel, to explore the effect of filling the wall of frame.(2) this paper uses frame-filled masonry shear wall model, infilled wall is the numberand arrangement of different cases of the model, and specification use infill walls to form ofload structure method is compared with.7models are built in the MIDAS/GEN software werecompared, this paper first to load form integral input model was established and the1wall,with wall filled with model2, model3pure framework, left two spans with load model4, twocross with infill wall model5, two right across the full load model6two, right across the wallfilled with model7compared with.(3) through calculation and analysis, comparison of the corresponding model, to studythe natural vibration period of filling wall of frame structure, displacement angle. Andsummarizes the effect of infill walls on the system of torsion.(4) through the response spectrum analysis of infilled into displacement, maximum levelof layer structure layer displacement and floor shear effect, at the same time, the structure ofnegative layer of the displacement, acceleration, story shear force time-history curve of output,to describe the effect of infilled walls, floor displacement, the relationship curve theacceleration and the shear force changed with time.
